PRECAUTIONPRECAUTIONSPrecaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"INFOID:0000000004685372

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS AIR BAG and SEAT BELT of this Service Manual. WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS AIR BAG. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERSWARNING: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

InspectionINSPECTION AFTER INSTALLATION

NINFOID:0000000004251139

Check accelerator pedal moves smoothly within the whole operation range when it is fully depressed and released. Check accelerator pedal securely returns to the fully released position. For the electrical inspection of accelerator pedal position sensor, refer to EC-467, "Description", EC-471, "Description" and EC-475, "Description". CAUTION: When harness connector of accelerator pedal position sensor is disconnected, perform Accelerator Pedal Released Position Learning. Refer to EC-18, "ACCELERATOR PEDAL RELEASED POSITION LEARNING : Description".

AUTOMATIC DRIVE POSITIONER SYSTEM : System DescriptionOUTLINE

INFOID:0000000004535061

The system automatically moves the driver seat, steering column and door mirror position by the driver seat control unit and the automatic drive positioner control unit. The driver seat control unit corresponds with the automatic drive positioner control unit by UART communication.Function Manual function Seat synchronization function Memory function Description The driving position (seat, steering column and door mirror position) can be adjusted by using the power seat switch, tilt & telescopic switch or door mirror remote control switch. The positions of the steering column and door mirror are adjusted to the proper position automatically while linking with manual operation [seat sliding, seat lifting (rear) or seat reclining]. The seat, steering column and outside mirror move to the stored driving position by pressing seat memory switch (1 or 2). The seat is made to advance when the seat back of driver seat is folded down and press the walkin switch. The seat is made to retreat to former position when the seat back of driver seat is folded up and press the walk-in switch. Perform memory operation, exiting operation and entry operation by Intelligent Key unlock operation or driver side door request switch unlock operation.
